Application October v8, 1945, Serial No. 620,958

My invention relates to protective mats for table-top gas ranges, and more particularly to the corner guards of such mats. and one object ,of the present invention is to provide a corner guard which maintains its correct position at all times.

A further object is to design the corner guard with means to lock it in place as it is positioned in the corner of the mat.

Another object is to construct the novel guard in a single piece properly tensioned to fit nrmly against the sides of the mat. v

With the above objects in view and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accom panying drawing, in which- Fig. 1 is a top plan view of a stove mat improvedwith the novel guard;

Fig. 2 is a bottom plan view Fig. 3 is a plan view of the guard alone;

Fig. 4 is a fragmental perspective view into a corner of the mat before the guard is secured therein; and

Fig. 5 is an enlarged duplication of one corner of Fig. 2, showing the guard secured in the mat.

Mats of the type herein considered are made with a. sheet metal top and an asbestos pad beneath the same. Thus, specific reference to the drawing indicates such a top at III and the pad at Il. In order to secure the pad to the top the latter is first inverted and extended with upward marginal flanges I2. The pad is then laid in the space between the flanges and the latter folded in by a suitable press to bear on the pad and hold the same to the top.

Since stove mats are generally rectangular. as shown, the matter of closing the flanges i2 at the corner of the mat is of importance.' While the flanges may be mitered end-to-end, there is always the chance that one end or another may spring away from the pad I l and cut the nngers when the affected mat corner is handled. It is therefore customary to cut the flanges away at the corner of the mat and insert a curved wire to supplement them and present a. smooth, rounded edge rather than the sharp, flange ends. While the folded iianges in the conventional stove mat are designed to hold the curved wire in place they often fail to do so, to the end that the wire gets loose or backs into the iiange folds, exposing the sharp flange ends fully as if no protective element were used.

In the novel embodiment the mitered ends of the flanges l2 are shown at Il. The flanges are 4 Claims. (Cl. 45-88A) 2 cut with slots I4 in the folding zone; and Fig. 5 shows that the slots of each pair of flanges communicate when the flanges are folded down o the pad il.

The novel guard is an arch li of heavy spring wire. extended with legs Il forming a slightly obtuse angle; and each leg is oifset inwardly from the arch by a crimp I1.

When the mat top is open-as in Fig. 4-and the pad il absent or spaced from the mat flanges ,as shown, it is possible to nt' the guard into the corner of the anges. As the guard is advanced toward the position shown, its crimps I1 trip over the ends of the slots I4 by momentarily springing the flanges, so that the arch projects outside the flanges. Since these are at right angles, the legs il of the guard are tensioned inwardly as the guard is advanced. The flanges are now folded down. exposing the arch Il prominently at the corner of the mat.

It will be evident that the fitting of the guard as described creates locking joints between the crimps i1 and the flange ends in a manner to positively check any tendency for the guard to recede into the mat; and the tension of the legs IC holds them firmly against the flange folds and prevents the guard from loosening or shifting in the corner of the mat. The guard is thus held firmly in the projected position and locked against recession. An emcient corner guard is thus had.

the same serving permanently to protect the' hands or fingers when engaging or holding the corners of the mat.

While I have described the invention along specific lines. various minor changes or rennements may be made therein without departing from its principle, and I desire to consider such changes ndreiinements as coming within the scope and spirit of the appended claims.

I claim: .l

1. A reinforcement for a sheet having a corner and marginal flanges adjacent to the corner and foldable back on the sheet, consisting of a unitary angle-shaped insert member having oppositeiydisposed free end parts adapted to seat in the bends of the flanges when these have been folded, the central portion of the insert being a loop sharply bent out from said end parts to form spaced notches for receiving the adjacent end portions of said bends.

2. 'I'he structure of claim 1, said loop being of.

arcuate form, and said anges being extended along the inner side of the loop to meet and overlap on a bias.

3. A mat-like article o! the class described in- 'l cluding a sheet member having a plurality o:

, into permanently folded relationship therewith, 5

said anges of each pair being formed to have their adjacent marginal edges disposed in obtuse A relationship with one another prior to the folding thereof. and a separate angle-shaped insert spring-like material to have a central portion and leg portions on the opposite ends thereof, said central portions portions consisting of loops which are sharply bent out from the inner ends of their attached leg portions so as to provide spaced notches therebetween which receive the adjacent 'portions of each pair of said flanges, said leg portions being tensloned inwardly by said folded lflanges so as to be locked rmly within the folds,

member for each of said corners, each of said m/ said adjacent end portions of adjacent flanges insert members being formed from a unitary rod of spring-like material to have a central portion and leg portions on the opposite ends thereof, said central portions consisting of loops lwhich are sharply bent out from the inner ends of their attached leg portions so as to provide spaced notches therebetween which receive the adjacent portions of each pair of said anges, said legportions being tensioned inwardly by said folded .being provided with extension parts adapted to overlap one another on a bias when said flanges are folded onto the sheet member with said loops projecting outwardly beyond the overlapping parts of said flanges.
